{$IFNDEF M_GENMENU}
{$DEFINE M_GENMENU}
{
  Main features:
  1) Independet from clist,may be used in any module.
  2) Module defined Exec and Check services.
  3) Menu with any level of popups,icons for root of popup.
  4) You may use measure/draw/processcommand even if menuobject is unknown.

  Idea of GenMenu module consists of that,
  it must be independet and offers only general menu purpose services:
  MO_CREATENEWMENUOBJECT
  MO_REMOVEMENUOBJECT
  MO_ADDNEWMENUITEM
  MO_REMOVEMENUITEM
  ...etc

  And then each module that want use and offer to others menu handling
  must create own services.For example i rewrited mainmenu and
  contactmenu code in clistmenus.c.If you look at code all functions
  are very identical, and vary only in check/exec services.

  So template set of function will like this:
  Remove<NameMenu>Item
  Add<NameMenu>Item
  Build<NameMenu>
  <NameMenu>ExecService
  <NameMenu>CheckService

  ExecService and CheckService used as callbacks when GenMenu must
  processcommand for menu item or decide to show or not item.This make
  GenMenu independet of which params must passed to service when user
  click on menu,this decide each module.

{
Analog to CLISTMENUITEM,but invented two params root and ownerdata.
root is used for creating any level popup menus,set to -1 to build
at first level and root=MenuItemHandle to place items in submenu
of this item.Must be used two new flags CMIF_ROOTPOPUP and CMIF_CHILDPOPUP
(defined in m_clist.h)

ownerdata is passed to callback services(ExecService and CheckService)
when building menu or processed command.

Changes:

Moved all general stuff to genmenu.c(m_genmenu.h,genmenu.h),
so removed all frames stuff.


Changes:

Contact menu item service called with wparam=hcontact,lparam=popupPosition -
plugin may add different menu items with some service.
(old behavior wparam=hcontact lparam=0)
